good material thanks melons5ube
The proposed new body clock measures DNA methylation -- the process by which genes are altered as the body's cells differentiate and their genetic programs change to meet new demands. Researchers pored over the DNA of some 8,000 samples from 51 different tissues and cells〓-- including blood, brain, muscle, heart, lungs, liver and pancreas --〓 to devise a formula by which DNA methylation could be used to determine the age of the tissue from which the tested cells are drawn.
